Important Questions on Collision

HARD
IMPORTANT

Explain elastic and inelastic collision. Obtain equations governing elastic collision in one-dimension and solve for final velocities of two colliding particles considering one particle to be at rest before collision.

MEDIUM
IMPORTANT

A metal ball of mass 2 kg moving with a speed of 36 km/hr has a head-on collision with a stationary ball of mass 3 kg. If after collision, both the balls move together, find the loss in kinetic energy due to collision.

HARD
IMPORTANT

A body of mass 5 kg moving with a velocity of 10 ms-1 collides with another body of mass 20 kg at rest and comes to rest. Find the velocity of the second body.

HARD
IMPORTANT

A plastic ball is dropped from a height of 1 m and rebounds several times from the floor. If 1.3s elapsed from the moment it is dropped to the second impact with the floor, what is the coefficient of restitution?

HARD
IMPORTANT

A ball is dropped from a height 'h' on a horizontal surface. It bounces up and down and finally comes to rest in time L. Show that

t=t01+c1-e

where 10 is the time taken for the first fall and e is the coefficient of restitution.

MEDIUM
IMPORTANT

A block of mass m moving at a speed v collides with another block of mass 2 m at rest. The lighter block comes to rest after collision. What is the coefficient of restitution?

EASY
IMPORTANT

A particle is dropped on a surface from is height of 9 m. If the coefficient of restitution is 0.5 What is the total distance covered by the particle before coming to rest.
